使用Android Native Native Activity的OpenCV2.4

我目前面临的问题与展示in this question相同，只是我使用的是2.4版而不是2.3.1。使用Android Native Native Activity的OpenCV2.4

我已经将原生活动（从ndk样本）转换为C++并修改了android.mk和application.mk。

我有同样的错误（与〜马特等等）。

当我读到问题的答案时，我意识到我需要添加OPENCV_INSTALL_MODULES:=on and OPENCV_LIB_TYPE:=STATIC（这是奇怪的，因为我有一个其他项目与本地openCV不需要这两条线）。

但它仍然无法正常工作。

Android.mk如下：

LOCAL_PATH := $(call my-dir) 

include $(CLEAR_VARS) 

OPENCV_LIB_TYPE:=STATIC 
OPENCV_INSTALL_MODULES:=on 

include includeOpenCV.mk 

ifeq ("$(wildcard $(OPENCV_MK_PATH))","") 
    #try to load OpenCV.mk from default install location 
    include $(TOOLCHAIN_PREBUILT_ROOT)/user/share/OpenCV/OpenCV.mk 
else 
    include $(OPENCV_MK_PATH) 
endif 

LOCAL_MODULE := native-activity 
LOCAL_SRC_FILES := main.cpp engine.cpp 
LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv1_CM 
LOCAL_STATIC_LIBRARIES += android_native_app_glue 


include $(BUILD_SHARED_LIBRARY) 

$(call import-module,android/native_app_glue)

，我发现了以下错误：

有什么我错过了吗？

尝试用

LOCAL_LDLIBS += -llog -landroid -lEGL -lGLESv1_CM

此修正我没有以前的错误了固定它，但代之以：由于无效的APK文件导致安装失败！请检查logcat输出了解更多详情。发布取消！在日志中：http://pastebin.com/Brj3n1BB – Tonial

我结束了尝试与本地等离子项目（其中显示完成通过写入位图），它运作良好.... – Tonial

我结束了与本土等离子项目（其中显示是通过位图写入完成）试图取代

LOCAL_LDLIBS := -llog -landroid -lEGL -lGLESv1_CM

，效果不错。

也许GLES与搞混了OpenCV。我不认为这两个项目之间有任何其他差异。

以某种方式解决了问题。不过，如果有人遇到同样的问题并解决它，我会有兴趣了解是什么原因造成的，以及如何解决这个问题。

尽管这是一个老问题，我遇到了同样的问题，并通过添加

LOCAL_LDLIBS += -lz # Compression library

要我Android.mk
